Optimism is quite stupid at this point. We are going to cross the 500,000 dead threshold. Hooray! It wasn't 1 million.
Hopefully the trend continues downward. Cases are dropping, deaths are lagging downward now. It seems the question is, are cases low enough (because they sure the heck aren't low) that new variants don't screw things up.
I worry, because at least around here, people have abandoned all caution whatsoever, and those who have been vaccinated seem especially convinced of their invulnerability. A vaccine-resistant strain, or just a new coronavirus, could put us back at square one very easily. Can you imagine the government trying to explain, at this juncture, that there is now essentially a
new disease to worry about and shut things down for? Vast swathes of the population would simply refuse to believe it, to take any self-protective action at all. But viruses are dangerous precisely because of their innate capacity to develop novel strains in a relatively short period of time.
